Simple Machine Forum - Blank Screen on Load / Switching Pages

[ThyRaven]

thank you for that code. I created the .htaccess and reloaded the page a couple times on a different PC using IE. I went into the -error.log file in the location you told me and found:

[Tue Sep 22 00:29:33 2015] [error] [client 62.210.107.201] File does not exist: /var/sentora/hostdata/brt/public_html/de-14_bigracktech_com/robots.txt
